Abstract
The authors analyze an annular element, which, from the values of the ratios among its dimensions, cannot be considered as a punched plate nor as a curved beam. The analysis is made by the finite element method taking account of the unilateral behavior of the constraints. Discretization takes place by means of tetrahedral elements at constant tension. The results are compared with those of continuous analysis which is a condition reached by using a particular expression of the tension function relative to a hollow circular cylinder of finite depth, validated by indefinite distributions of tension agents on the sections of the end of the cylinder.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
